Quickboot Device Tree

Quickboot (QB) has a data driven framework which uses the device tree to configure device drivers and clocks in various configurations. The QB build process generates the device tree source and the QB device tree binary (DTB) files. The device tree source has a name that is based on the device name, e.g. e3550. The QB device tree binary is appended to QB bootloader binary, qb_cpu.bin, during flashing or offline image creation to generate the final binary, qb.bin.
